Be it known that we, ELLERY I. ANDERSON ,and OSCAR M. MORRILL, citizensof the United States, residing at Charleston in the county of Charlestonand State of South Carolina, have invented new and useful Improvementsin This invention; resides in the novel features Aof construction ,setforth in the following fiann'exed drawings, in which-'- Y Figure lisasectional plan viewr of the lock.4 Fig'. 2 is asection along fw w, Fig.1..

' lining.

The doori is adapted to be held Shut-orto y the jamb 2 by bolt3,havingahollow or tubular tailpieeeei, and normally held or moved to lockingposition'by spring 5. The door-is Qmortised to receive a lining or tube6, in which the bolt can play." 'A slot-and-pin connection 7 and 8 canbe'made to suitably limit the play of theLbolt.

The tailpiece 4 and vlining 6, as seen inFig. 7, have cuts or passages 9andv 10 for a purpose presently explained, and said tailpiece 4 alsohasa cross-piece 11,i-n form of a rod, extended across the chamber orinterior of this hollow tailpiece.

The door at its inn'er side is shown with escutcheo'n'12'and at itsouter side with es- .cutcheon-13, suitably fastened or screwed inplacein 'anyisuitable manner. Through the door extends atiibeor'housing14, shown with theouter .knob fixed or castthere'to. The

. inner or removable knbblcan be secured in suitable way, asfbyshoulder'l' and screw 18,

Thespindle is longitudinally movable in tube 14, and when shifted tocarryor slide`lug'20l ;through the passages 9 and 10, Fig. 7, so that thelugrestsv in the hollow tail 4, Fig. 4, the spindle when rotated to carrylug against l cross-piece 11 will withdraw or open the 'bolt X,4

'lhespring 3S tends to move the spindle 19 inward or into active position.The tube 14; is of course suitably slotted to allow the lug 20 to moveback and forth with the spindle 12). The tube M, while rotary, has Thelip 2S is fixed or cast in the tube 1l.

lVhat we claim as new, and desire to secure by Letters Patent, is

l. The combination with a bolt having a iransversely-arranged passage,of a longitudinallyanovable spring-pressed spindle having a lateralrigidly-attaehed lug forentering said passage to actuate the bolt, adevice for holding the spindle with its lug outof engagement with thebolt, and means for releasing said holding device to permit the springacting on the spindle to aetuate the latter and move the lug intoengagement with ihebell, substantially as described.

2. The combination with a bolt having a transverse] y-arran ged passage, of a knob-earrying tube, a tubular spindle arranged in theknob-carrying tube, rotating therewith and movable longitudinallyindependent thereof, a lug rigidly secured to and projecting laterallyfrom the tubular spindle to enter the said passage of the bolt, a springfor moving the spindle in one direction, a device for holding thespindle against the tension of the spring, and lneans foroperating saiddevice to release the spindle and permit its spring to operate and causethe lug to enter the said passage, substantially as described.

3. A tube orhousing having a lip, a spindle having a catch for engagingthe lip, a lug on the spindle, and a bolt, said spindle being madelongitudinally movable to carry the lug into and out of engagementwiththe bolt and said catch being made rotatable to eleai' or move to oneside of the lip substantially as deseribed.

4. A tube or housing having'a lip, a longitudinally-movable spindlehaving a catch for engaging the lip, a lug on the spindle, a boltadapted to be engaged by the lug, a rotary stem in the spindle and t0which the catch is connected, and a button or handle at one end` of thespindle for rotating said stem, the other end of the spindle beingadapted for the insertion of a key substantially as described.

5. A tube or housing having a lip, a longitudinally-movable spindlehaving a catch for engaging the lip, a lug on the spindle, a boltadapted to be engaged by the lug, a rotary stein in the spindle forsupporting the catch, a button or handle for the stein, and a keybloeliforked for the respective engagement of the catch and of akeysubstantially as described.

(i. A tube or housinghaving alip, a spindle having a catch for engagingthe lip, a lng on the spindle, anda. bolt adapted to be engaged by thelug, said tube being slotted and said spindle having a handle or triggerextended through the slet substantially as described.

7. A door having a nlortise, a bolt in the mortise, a spindle7 and a lugon the spindle adapted to engage the bolt7 said door having a slot orseat for the lng and said spindle being longitudinally movable to carrythe lug from the slet to the bolt substantially as described.

In testimony whereof we have hereunto set our handsin the presence oltwo subscribing witnesses.
